Sorry I took too long to get back on this, but it's been busy here. 5. : The error when running the CAL lab indeed disappeared
6. : The Tabula addon also fails when it's the first thing run after starting J. So I'd be surprised it's a conflict of predefined verbs. As the error is the same for any button clicked, and it's an error in chkgl2, maybe it's due to the works on jQt and the GL stuff?
